Description of drawings
Accompanying drawing is the structural representation of a kind of high-temperature steam of the present utility model and gas at normal temperature and water three-phase medium safety valve testing platform.
Embodiment
Referring to accompanying drawing, the utility model is a kind of high-temperature steam and gas at normal temperature and water three-phase medium safety valve testing platform, it comprises band compressed steel bottle 2, force (forcing) pump 20, water storage cylinder 4, single tube direct current cooker 6, Gas appliance 17, safety valve testing pedestal 11 and connecting line, also can connect industrial computer 26.
Be connected by pipeline between water storage cylinder 4 and the single tube direct current cooker 6, stop valve 18 is housed on this pipeline.The rear end of single tube direct current cooker 6 connects a verification admission passage 7, at the rear end of verification admission passage 7 setting pressure and flow control valve 14, is used for regulating pressure and displacement.Single tube direct current cooker 6 is a kind of small-sized single pipeloop high voltage direct current boilers that produce the combustion type heating of steam.On the pipeline that between single tube direct current cooker 6 and safety valve testing pedestal 11, is connected initial steam pressure table 8 is housed, to show force value.
Before the band compressed steel bottle 2 gas booster 1 is housed.Band compressed steel bottle 2 is connected with water storage cylinder 4 by pipeline, and stop valve 3 is housed on this pipeline.Water storage cylinder 4 also is equipped with water drain valve 19 by pipeline.
Safety valve testing pedestal 11 is placed on the pipeline that is connected with 6 outlets of single tube direct current cooker.At safety valve testing pedestal 11 with on point for measuring temperature 9,12 is set respectively, for example can be arranged on suction flange place, the housing by verification safety valve 10.Be verified the safety valve 10 outside cases of installing, by electrical heating control, the simulating Safety valve moves bad border temperature.
Checking procedure of the present utility model and result can be shown, write down, store, be printed by industrial computer, and its operation operating mode can be controlled by industrial computer.
Number in the figure 13 is electrical heating switches, the 21st, and moisturizing source, the 22nd, setting-out valve, the 23rd, air release, the 24th, certificated valve, the 25th, boost gauge.
The course of work of safety valve testing platform of the present utility model is as follows:
The safety valve 10 that is verified is fixed on the verification pedestal 11, pressurized air in the band compressed steel bottle 2 of supercharging or nitrogen are through behind the stop valve of opening 3, pressure enters water storage cylinder 4 and charges into certain pressure, gas control valve 16, stop valve 18 all are closed condition at this moment, and the pressure in the water storage cylinder 4 are elevated to required test pressure.Open variable valve 14 a little after force (forcing) pump 20 starts, standard-sized sheet stop valve 18 makes normal-temperature water direct current cooker 6 backs of flowing through be oozed by variable valve 14.Open 17 pairs of single tube direct current cookers of Gas appliance, 6 heating pipeloops then, make pipe be heated into steam and overflow through variable valve 14.The flame size aperture of Gas appliance 17 has determined the temperature of the steam that produces.The opening control system pressure of variable valve 14.
